First-order flows and stabilisation equations for non-BPS extremal black holes
Pietro Galli, Kevin Goldstein, Stefanos Katmadas +1
We derive a generalised form of flow equations for extremal static and rotating non-BPS black holes in four-dimensional ungauged N = 2 supergravity coupled to vector multiplets. Fo…
New supersymmetric higher-derivative couplings: Full N=2 superspace does not count!
Bernard de Wit, Stefanos Katmadas, Maaike van Zalk
An extended class of N=2 locally supersymmetric invariants with higher-derivative couplings based on full superspace integrals, is constructed. These invariants may depend on unres…
Almost BPS black holes
Kevin Goldstein, Stefanos Katmadas
We study non-BPS black hole solutions to ungauged supergravity with 8 supercharges coupled to vector multiplets in four and five dimensions. We identify a large class of five dimen…
